Abstract
A method for estimating failed sensor readings from available unfailed sensor outputs is presented and evaluated. The method uses a bank of discrete, linear Kalman filters (one for each sensor monitored) and an optimal combination logic to perform the estimation. Performance of the proposed technique is evaluated using data from a small-scale nuclear power plant. Potential applications to safety parameter display systems are addressed.Keywords
